Blind Drain-Semimember Locking Mechanism for Trench Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trench half-elements face challenges in precise assembly due to small dimensional deviations, leading to labor-intensive and costly repairs or scrapping, as they require accurate positioning of numerous columns which can be affected by bending or production-related issues.
Innovation Solution
The design incorporates a base grid with columns featuring complementary connecting elements, including projections and receptacles, allowing for secure and precise connection of trench half-elements through a locking mechanism, ensuring accurate alignment and firm assembly even with slight inaccuracies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional connecting elements are used without locking projections, then the assembly process is simpler, but the connection precision and stability deteriorate, requiring labor-intensive rework for minor deviations
Solution Approach 1:
The locking projection on the first connecting element automatically engages with the second connecting element during assembly, creating a self-securing connection that maintains precision without requiring additional fastening operations or complex alignment procedures
Solution Approach 2:
The locking projection acts as an intermediary mechanical feature that mediates between the two connecting elements, ensuring precise engagement and stable connection while simplifying the overall assembly process through automatic locking
2Stability of the object's composition
If columns are made rigid to maintain shape, then structural stability is improved, but susceptibility to bending from frozen stresses or production issues increases
Solution Approach 1:
The connection design anticipates potential dimensional deviations from production or storage stresses by incorporating a locking mechanism that accommodates minor variations, preventing complete assembly failure before the problem manifests
3Manufacturing precision
If multiple columns are precisely positioned for proper assembly, then the drainage trench assembly quality is improved, but the time and effort required for assembly increases
Solution Approach 1:
The fitting projections and receptacles on the columns perform self-alignment during assembly, automatically positioning columns correctly relative to each other without requiring manual measurement or adjustment, thereby maintaining precision while reducing assembly time
